Grade stomacher bags

Grade’s homogeniser/blender and separator bags come in a range of sizes from 80 to 3500 mL and are available with straight or curved bottoms and with or without filters. Also available are Grade disposable straws to pipette samples after homogenisation.

The bags are suitable for all types of blender machines and are made to exacting standards. Laboratories worldwide use the bags due to their durable composition and the low likelihood of bags bursting when in use. They are manufactured under an ISO 9001 approved quality control system and have a negligible failure rate.

Grade has made a robust bag by using the correct blend of polymers (high-quality, food-grade LDPE) for good strength and elasticity. Bags are tested at up to eight times the normal usage to ensure each individually numbered and traceable batch is up to standard.

The easy-to-open double size (4 mm) seal makes any faults totally visible, giving users the added security of no leakage. The bags are gamma irradiated for sample integrity and have a minimum shelf life of five years.

Standard homogeniser/blender bags are available in three sizes: 80, 400 and 3500 mL. Separator bags come in 400 mL sizes with curved or straight bottoms.
